"strcmp()", "strcasecmp()", and "memcmp()" don't return booleans; don't
test their results as if they did.
Use "guint8", not "guchar", for a pointer to (one or more) 8-bit bytes.

sequence numbers or offsets and are thus assumed to be received in order
with no duplicates or dropped fragments (e.g., for NetBIOS Frame, where
802.2 LLC guarantees in-order delivery to NetBIOS with no duplicates or
dropped fragments).
"show_fragment_tree()' and "show_fragment_seq_tree()" don't modify the
"fragment_items" to which the "fit" argument points, so make that
argument a "const fragment_items *".
Make all the "fragment_items" tables "static" (as they're not used
outside the modules defining them) and "const" (as they're not
modified).
Add support for reassembly of NetBIOS fragmented requests and responses.
Get rid of an unnecessary include of "packet-tr.c" in the NetBIOS
dissector, and make its table of dissection function pointers static.
Fix some typos in the AppleTalk and NetBIOS dissectors.

but for stuff reassembled with "fragment_add_seq()" or
"fragment_add_seq_check()".
Add a "fragment tag" string to the "fragment_items", so that packets
with fragmentation errors can be properly flagged as having "Illegal
fragments" or "Illegal segments" depending on the term used with the
protocol in question.
Make all the dissectors that can use "show_fragment_tree()" or
"show_fragment_seq_tree()", and don't already use them, do so.

task of creating a fregment tree for the fragmented packets.
Having this identical code to create this tree in every dissector that does
PDU reassembly is a huge waste and duplication of code.

regardless of whether they're the first frame we see in a reassembly or
not - put all but the last fragment into the hash table (so subsequent
frames with the same reassembly ID don't get misdissected as
unfragmented frames), return the head of the fragment list for the first
fragment and NULL for all other fragments (so the first fragment gets
dissected as a fragmented packet), and unhash the fragment head from the
reassembly hash table when we see the last fragment.

least some of the reassembly mechanism, so we can deal with both bogus
and real last fragment (display the bogus ones as unfragmented frames,
treat the real ones as fragments).

"frame_data" structure for the frame as the key structure, and use the
frame number in that field as the key. (We could be even cheesier and
use the frame number as the key, with casts.)
When we move an entry from the hash table of reassemblies to the hash
table of reassembled packets, free the key structure for the first hash
table. (This doesn't plug a leak, as they get freed when you
reinitialize the data structures, but it does reduce the memory needed
for them to the amount needed for in-progress reassemblies rather than
the amount needed for all reassemblies.)

packets, using the reassembly ID and the frame number of the final frame
as the key. There is no guarantee that reassembly IDs won't be reused,
even when talking between the same source and destination address; if,
once reassembly is complete, the "fragment_data" structure is moved to
the latter hash table, this will keep reused reassembly IDs from causing
mis-reassembly.
Add a routine "fragment_add_seq_check()", which
if a fragment has the "more fragments" flag not set but is the
first fragment of a reassembly, treats that as a non-fragmented
frame, allocating a "fragment_data" structure for the reassembly
but not attaching any fragment to it, and adding it to a
reassembled packet list;
if a packet has been reassembled, removes it from the table of
reassemblies and moves it to the table of reassembled packets;
if the frame's been seen already, looks it up in the table of
reassembled packets rather than the table of reassemblies.
Add reassembly support for fragmented 802.11 frames. Use
"fragment_add_seq_check()" to cope with the fact that some
hardware+drivers apparently hands us reassembled frames with a non-zero
fragment number and the "more fragments" bit clear (as if it puts the
802.11 header of the *last* fragment onto the reassembled data).

reassembled TCP data being able to indicate that they need still more
reassembly, so that, for example, a dissector can indicate that it needs
reassembly in order to dissect a header that says how long the PDU is
and, when that reassembly is done and it dissects the header, it can
then indicate that it needs more reassembly to get the entire PDU.

"epan/..." pathnames, so as to avoid collisions with header files in any
of the directories in which we look (e.g., "proto.h", as some other
package has its own "proto.h" file which it installs in the top-level
include directory).
Don't add "-I" flags to search "epan", as that's no longer necessary
(and we want includes of "epan" headers to fail if the "epan/" is left
out, so that we don't re-introduce includes lacking "epan/").

Add a few small functions to reassemble.c to cope with protocols
where the total length of defragmented PDUs are specified in the
first fragment (all previous uses of reassembly has been for
PDUs where the last fragment is signalled by a flag in the
header for the last fragment).
Add a few small functions to reassemble.c to abort-and-delete
defragmentation of PDUs and also detect IF a PDU is currently
being defragmented. (Useful for PDUs where the "unique"
identifier is rather ununique, or may be reused often enough so
it can be a problem for Ethereal.)
Change where NT Cancel presents its Cancelation-to output, and
makes the three trans secondary requests also output similar
information.

dissectors to use it, from Ronnie Sahlberg, with additional changes to
handle the case where a frame contains messages that don't run past the
end followed by one that does and where a reassembled chunk has, at the
end, a message that runs past the end of that chunk (because the
reassembly was for an earlier message).
